  • Replacing a shared spreadsheet used by a team that has outgrown it but cannot justify a developer to build a bespoke internal toolnot Argo CD
  • Inventory, asset or case tracking for a small operations team that needs roles, forms and a record of who changed whatnot Argo CD
  • A registration or booking application for an association, school or non-profit where the user count is large and the record count stays modestnot Argo CD

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Argo CD

  • The quick start installation requires the --server-side and --force-conflicts flags due to CRD size limitations, per argo-cd.readthedocs.io, a constraint the documentation states explicitly

Knack

  • Plans are capped by stored records, so an application that logs events or keeps history rather than current state climbs tiers on data volume alone, and archiving old records becomes a permanent maintenance chore rather than a one-off
  • API access is capped per day, at 1,000 calls on the entry plan and 10,000 at the Corporate tier, so a scheduled sync or a busy automation can exhaust the day's quota before the working day ends and integrations then fail silently
  • The application itself cannot be exported or self-hosted; records can be downloaded but the pages, roles, flows and business logic exist only inside Knack, so outgrowing the platform means rebuilding the app rather than moving it
  • Customisation beyond the builder is limited to injected CSS and JavaScript that Knack's support does not cover, so any non-standard interface behaviour becomes yours to maintain against a DOM the vendor can change without warning
  • Compliance capabilities that regulated buyers assume are baseline, HIPAA and GovCloud options, advanced SSO, IP restrictions and private environments, are gated to the Corporate and Enterprise tiers, so a small regulated pilot cannot legitimately start on an entry plan

Answered from the vendors’ own pages

Argo CD: What is the cost of Argo CD?

Argo CD is open source and free to use. No licensing fees, subscription charges, or commercial restrictions apply. The project is maintained by the CNCF community.

Source
Knack: Is Knack charged per user?

No. User accounts are unlimited on all plans. Plans are bounded by stored record count, file storage, API calls per day and automation transactions.

Argo CD: How frequently does Argo CD poll Git repositories by default?

Argo CD checks Git and Helm repositories every 3 minutes by default to detect configuration changes, enabling timely deployment of updates.

Source
Knack: What happens when I exceed the record limit?

You move to a higher tier or reduce stored records. Because the limit is on data rather than people, apps that accumulate history hit it while apps that track a fixed set of entities generally do not.

Knack: Can I export my application or self-host it?

You can export record data. The application itself, its pages, roles, permissions and flows, is not exportable and cannot be self-hosted, so leaving means rebuilding elsewhere.

Knack: Is it suitable for public-facing portals?

That is its strongest case, because logins are unlimited and role-based permissions are built in. The constraint is record volume and API throughput, not audience size.

Knack: Can I use it for regulated data?

HIPAA-aligned and government cloud options exist but only on the Enterprise tier, along with private server environments. Lower tiers should not be used for regulated workloads.
